MAGLift™ Rotor Stabilizer

The MAGLift™ rotor stabilizer uses the Magnus effect: a spinning rotor moving through water creates differential pressure and lift. Mounted at the turn of the bilge, the rotor is deployed perpendicular to the hull, and its spin direction and speed are varied to counter roll. When not in use it stows parallel to the hull to reduce drag. Quantum states it has the highest lift-force ratio of its systems.

Key features

• Operating range from Zero Speed™ to 14 knots
• Hull pocket, semi-pocket or no-pocket installation
• Seven sensors monitor rotor position, angular velocity and rotation speed
• Automatic retraction on impact; suitable for vessels requiring ice classification
• Models ML200 to ML600

Applications

Slow-speed, loitering, zero-speed and shallow-water operation; often paired with XT™ Fins on yachts over 100 m. A pair of ML460 rotors is fitted to the 73 m expedition cruise ship National Geographic Venture.
